standardize your start points at someplace appropriate. For example,
start the Oak St. loop at the HS. While the loop goes around, you're
gonna want some place to meet/park to ride the loop (unless you live on it
like I do).

Also, unless there's a regularly scheduled club ride, you might also
list all loops as starting from the largest town on the loop. So the
"West Springfield" loop would also start at Newport HS, even though it
goes through Sunapee, Georges Mills, W. Springfield and Grantham. The
"Tyson" loop, however, would be listed as starting from the Ascutney
Park and Ride, even though it goes through Ludlow. (For those of you
who haven't ridden it, this loop includes a 6-mile climb, on Tyson Rd.
from S. Reading to Echo Lake, that takes about a half hour and is over
15% at some points.)
